AI Technical Summary
The existing fastening nuts are prone to damaging the threads on the rotary cylinder during installation, making it impossible to screw the locking nut into other positions that require adjustment.
The system employs two nut bodies and a locking assembly arranged side by side. The locking screws apply pressure through the second threaded holes evenly distributed on the outer circumference of the nut bodies, achieving uniform force on the threads and preventing damage.
It provides protection for the screw threads, ensuring a secure installation without damaging the threads, and is suitable for industrial applications.

[0016] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0017] Please refer to Figure 2 With Figure 3 A fastening nut, comprising
[0018] Two nut bodies 10 arranged side by side, the nut body 10 comprises a first threaded hole 101 for connecting with an external device;
[0019] A locking assembly connected with the two nut bodies 10, used for pressing against the end face of the nut body 10 in the installed state.
[0020] Specifically, during operation, the two nut bodies 10 are installed in the corresponding threaded column of the external device through the first threaded hole 101, in this embodiment, the connecting shaft of the rotary cylinder, after installation, the end faces of the two nut bodies 10 are pressed by the locking assembly, so that the end faces of the two nut bodies 10 are tightly pressed on the threads on the connecting shaft, thereby being stably fixed on the connecting shaft, and the threads are uniformly stressed, effectively protecting the threads.
[0021] The utility model relates to a fastening nut, through the setting of two nut bodies 10 and locking assembly, install stable, low to the injury of screw thread simultaneously, effectively the protection of screw thread is suitable for industrial application.
[0022] In one specific embodiment, the locking assembly includes locking screw 20, the outer periphery of the nut body 10 is equipped with the second threaded hole for the locking screw 20 passes, and in the installation state, the locking screw 20 is installed in the second threaded hole of the two nut body 10 corresponding.
[0023] Specifically, when the two nut bodies 10 are installed on the connecting shaft, the locking screw 20 is tightened to make the two screw bodies close to each other, so that the nut body 10 is pressed on the screw thread, and the screw thread is uniformly stressed, and the purpose of fastening is achieved without damaging the screw thread.
[0024] In one specific embodiment, the second threaded hole is provided with a plurality of second threaded holes on the outer periphery of the nut body 10, and is uniformly distributed along the outer periphery of the nut body 10. In this embodiment, the locking force of the nut body 10 is effectively improved by the arrangement of the plurality of second threaded holes and the cooperation of the locking screw 20.
[0025] The utility model relates to a fastening nut, through the setting of two nut bodies 10 and locking assembly, install stable, low to the injury of screw thread simultaneously, effectively the protection of screw thread is suitable for industrial application.
[0026] The above embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it can not be understood as the limitation of the utility model patent scope.
